my version would be this if I start from E but i haven't figured the chords while playing the original so there could be slight variations. scale and all.
EAEE-pyaar kar liya..
EEBE-teri meri umra me kisne......
EEBE-tere honth mere honth..
EBAE-dil ki tarah jism bhi...
EEBE-is se pehale kya kabhi....
